Geelong superstar Patrick Dangerfield has traded in his number 35 in the warm-up before tonight's clash at the MCG.
He donned the number 0 on his back during the warm up in support of youth homelessness charity 'Ladder'.
The number '0' represents the acceptable number of homeless youths.
He is now wearing his usual number 35 for the game.
The Cats are taking on the Tigers at the MCG in front of a bumper crowd in excess of 90,000 people.
Dangerfield is playing in his 200th AFL game tonight.
